Nuclear size and rapidity dependence of the saturation scale from QCD evolution and experimental data

, 2005
The solutions of the Balitsky-Kovchegov evolution equations are studied numerically and compared with known analytical estimations. The rapidity and nuclear size dependences of the saturation scale are obtained for the cases of fixed and running coupling

A Monolithic Finite Element Formulation for Magnetohydrodynamics Involving a Compressible Fluid

Fluids, 2022
This work develops a new monolithic finite-element-based strategy for magnetohydrodynamics (MHD) involving a compressible fluid based on a continuous velocity–pressure formulation. The entire formulation is within a nodal finite element framework, and is

Nature of the metal-nonmetal transition in metal-ammonia solutions. I. Solvated electrons at low metal concentrations

, 2007
Using a theory of polarizable fluids, we extend a variational treatment of an excess electron to the many-electron case corresponding to finite metal concentrations in metal-ammonia solutions (MAS).

Dynamics of liquid nano-threads : fluctuation-driven instability and rupture [PDF]

, 2020
The instability and rupture of nanoscale liquid threads is shown to strongly depend on thermal fluctuations. These fluctuations are naturally occurring within molecular dynamics (MD) simulations and can be incorporated via fluctuating hydrodynamics into ...

To the Problem of Discontinuous Solutions in Applied Mathematics

Mathematics, 2023
This paper addresses discontinuities in the solutions of mathematical physics that describe actual processes and are not observed in experiments. The appearance of discontinuities is associated in this paper with the classical differential calculus based

Wave model for longitudinal dispersion: Application to the laminar-flow tubular reactor [PDF]

, 1996
The wave model for longitudinal dispersion, published elsewhere as an alternative to the commonly used dispersed plug-flow model, is applied to the classic case of the laminar-flow tubular reactor.
